Applications using measured values of the transport properties of concrete I: predicting the durability of reinforced concrete

Abstract

The transport properties control the durability of concrete and, in particular, the corrosion of reinforcement. The mechanisms for this are discussed and experimental measurements of corrosion using linear polarisation are presented. These are then correlated with a number of transport related properties. The use of the Nordtest NT Build-492 and the ASTM C1202 electrical tests for predicting corrosion is then considered. It is shown that the Nordtest suffers from the same problems as the ASTM described in Chapters 1012. However, it is concluded that durability models such as the NRMCE Life-365 model have similar ...
